Endosomolytic Solutions for PNA Cell Delivery

Endosomolytic Solutions for PNA Cell Delivery

The poor cellular uptake of PNA can be improved by combining some carrier molecules, but the efficacy of these PNA conjugates is still retained by endosomes. The bioavailability of PNA conjugates can be improved through the use of endosomalytic strategies. Creative Peptides provides two endosomalytic solutions to further promote the cellular uptake of PNA.

Our Solutions

Facing the challenge that the PNA delivered from the endosomal compartment can be efficiently and functionally delivered to the cell, Creative Peptides provides two solutions that can be easily applied to PNA cell delivery to improve the intracellular PNA bioavailability.

  • Chloroquine Treatment

    Chloroquine can interfere with immune cells called macrophages, which are used by the body to recognize tiny foreign objects and destroy them. Therefore, chloroquine can reduce the immune clearance of PNA, leading to an increase in the accumulation of PNA drugs in the cell.

  • Photochemical Internalization Treatment

    PCI technology consists of light-sensitive compounds, which are incorporated into endocytic vesicles during the uptake of PNA molecules through endocytosis. After being irradiated with light, the photosensitizer is activated, which causes the release of PNA into the cytoplasm, which can achieve the goal of PNA.
